In a collaborative effort, Shanghai Jiao Tong University and the Shanghai Institute of Ceramics at the Chinese Academy of Sciences have unveiled a groundbreaking discovery. They have identified a group of inorganic semiconductor materials that exhibit exceptional plastic deformation and processing capabilities within a low-temperature range (approximately below 200°C). The research team innovatively adapted the classic "warm processing" technique, traditionally employed for metallic materials, to brittle semiconductors at room temperature. This adaptation has led to the successful fabrication of high-quality, self-supporting, and adjustable-thickness high-performance semiconductor films. Building upon this significant achievement, the team has further developed thermoelectric devices with impressive output power density, thereby opening up a novel avenue for the processing and manufacturing of brittle semiconductors.
